At 12B Clean, we don’t shy away from anything—and I mean absolutely anything—when it comes to cleaning. Our three departments are staffed by intelligent and highly trained people who know exactly what is expected of them.
Our Workers are highly skilled in routine cleaning tasks. Vacation resorts, schools, commercial buildings, offices, student housing, etc., are their daily work environment. The Masters are trained for more specialized and demanding cleaning tasks. Finally, the Profs are trained for highly specialized work, such as crime scene cleaning at the sites of murder, crime, death, and suicide, as well as dealing with the odor of decomposition, trauma, and biohazards. They, too, are on call 24/7 to provide immediate assistance anywhere in the Netherlands.

Nice to meet you. We are Jack Oosterwaal and Michael de Bruine, co-founders of 12B Clean, a cleaning company serving Groningen and other areas. We’ve been inseparable in business for years. We once shared a dream: to start our own company in the cleaning industry. We wanted to approach it much better, much more comprehensively, and much more humanely than any other company. If you want something, you have to go for it—and here’s the result. Our employees are well compensated, receive training and recognition, and go out to our clients with diplomas in hand.
They value intelligent and skilled people in their workforce. Together, we’re experts in every aspect of the cleaning industry—from routine cleaning to specialized tasks. And we offer all of this at a highly competitive price. With effective organization, this is a win-win model for everyone involved.
